Analysis of the performance of the agitator: High-speed agitators are often used in the manufacture of chemical machinery. Such agitators can be divided into two categories: the blades are vertically rotated in a plane; the blades and the rotating planar structure are inclined or angled. High-speed agitators can be used in light wall mixing tanks and mixing tanks with different tank accessories. Furthermore, an agitator with inclined vanes can be used for agitating irrigation with a draft tube. The three-bladed agitator is composed of three flat blades welded by a sleeve having an inner diameter d and an outer diameter d, the rotation plane of the blade and the agitator is at an angle of 24°, and the width b of the agitator blade is taken as 0.2d. . In the practice of chemical machinery manufacturing, an equal pitch propeller type agitator is used, and its blades may be cast wing sections or welded with equal thickness metal materials. The propeller type agitator having an equal pitch P has an inner diameter d and an outer diameter d. On the outer surface of the hub, three flat blades of width b are uniformly welded at an angle of 120°.
After long-term experiments, it is not recommended to use this type of agitator because the cast disorderly paddle agitator and the agitator with equal thickness blades require special casting and complicated stamping processes. In terms of hydrodynamic performance, it is only slightly better than a three-bladed agitator, so it should be replaced with a three-bladed agitator.
